MOWINGhMACHINE.

, Application-filed May 17, 1911. Serial No. 627,738..

To all whom #may concern.'

Be it known that I, O'rro CZARAN, a. subject of the Emperor of Austria-Hungary, residing at Glendale, Long Island, in the 5 county of Queens and State of New York,

have invented certain new and useful Improvements in Mowing-Machines, of which the following is a specification.

The present invention pertains to mowing machines and has for its principal object to so construct the same so as to enable of their being propelled and at the same time operated by motor power.

Another object o-f my invention is to provide a construction enabling the machine being folded upto render it easily transportable on narrow roads.A

With these and other objects in view,`my invention consists in the construction, combinatioii and arrangement of `parts as hereinafter fully specified and claimed.

In the accompanying drawing, which` forms a part of this specication, and in which 'similar reference numerals denote corresponding parts, Figure 1 is a rear elevation of the mowin'gmachine in operative position; Fig. 2 is a top plan viewthereof; Fig. 3 is a side elevation; Fig. 4 is a rear elevation of the folded mowing machine, ready for transport and Fig. 5 is a detail. The mowing machine comprises a frame supporting the grain carrier or elevator and lconstructed of two sect-ions 1, 2 pivoted together'at 3 so that the frame sect-ion 1 may be lift-ed into the position shown in Fig. 4. The section 1 hasthe usual extension for. the elevator", which I also .make of two sect-ions 1, 12,*each formed with flanges'l3 to be rigidly "joinedwhen the frameis in operative position and to be detached prior to the lifting of the section 1 into the position shown in Fig. 4. The grain carrier or elevator being of ordinary construction, as forinstance, of the type-used in the well known McCormick mowing machines and not forming a part of my invention, I shall no t enter into the details thereof.

. Along the front longitudinal edge of t-he section 1 of the elevator frame'are arranged in well known manner the ordinary reciprocatory knives 6. The elevator frame is arranged on a transport truck 7 substantially of rectangular shape, which is formed in front with a triangular extension 8. The x 9 of this triangular extension carries a 1" blfurcated frame 10 in which 'a singl wheel t-ruck is supported. Suitable means may be provided for the steeringv of the said wheel.

and forsecuring it in the direction of travel. Atthe rear of the frame 7 a shaft 12 is r0- tatively mounted transversely thereto which at one end loosely carries a t-ruck wheel 13 -and at t-he opposite end is providedwith a flange 14" or other suitable means to enable the removable attachment of the other truck 11 constituting the steering wheel of the` wheel 13 when the machine is folded up for v the transport 4(see dotted lines Fig. 2).

When the machine is unfolded for use the wheel 13 is' removed and instead a spindle' 14 having a corresponding .flange 142 or `other suit-able means is fixed to the spindle- 12 Vin linear extensionof the latter, and the second truck wheel 13' is fixed to the free end of said extension (see full linesv inFig.

2). The elevator frame is provided at its rear with several curved -arms 15, 16, 17 supporting the spindle 14 and lformed with suitable bearing therefor. These arms may be all rigidly xed to' the frame or may be supported on pivots 17 to be capable of being swung horizontally on the removal of t-he spindle 14 prior to folding up themachine. On the opposite side, the elevator frame is provided with one or more curved arms 18, the center of their curvature being the a-Xis of the shaft 12, which are rovided with suitable guide grooves 18. (,)pposite thereto guide members 19 project from the truck frame slidably engaging the guide grooves 18 of' said arms and permitting of the elevator frame being swung either up or down around the shaft' 12 in order to adjust Ythe position of the knives according as the grain is to be cut at a higher or lower point. The adjustment of the frame around theshaft 12 may be accomplished by' any suitable means, as for instance, a nut 20 working on a stationary screw 21 (Fig. 3).

In front of the elevator frame, the reel 22 mitted bysuitable transmission means -to' the.

truck wheels, etc. In order to allow of the truck turning easily around a corner, I provide the following arrangement:

Parallel to the wheel shaft 12 is a sectional spindle 26, 26 the two sections of which are coupled by means of a suitable friction coupling 262. The motor shaft is connected by suitable gears to one, of the sections, as 26', of said spindle and said section in its turn is operatively connected to the loose truck wheel 13. The other section 26 of the sectional spindle is connected by suitable transmission gears to the main truck shaft 12. It will be seen that when the truck is steered to turn around one of the truck wheels, say wheel 13', the wheel 13 will continue to revolve while the wheel 13 remains stationary.

` The means 28 whereby reciprocating motion is transmitted from the motor by suitable gears to the lmives may be so connected to the knife mechanism that it will not interfere with the folding of the section 1 and the adjustment of the elevator around the spindle 12.

At the rear, the truck frame is provided with an auxiliary truck wheel 29 which is yieldingly supported in the truck, as for instance, by means of a spring actuated frame (Fig. 5) and which wheel is designed to support the rear of the machine, particularly when the latter is unfolded or in the position shown in Fig. 2.

I do not wish to limit myself to the par-g ticular construction described and shown,

since various modications may be made by those skilled in the art without departing from the spirit of my invention.

What I claim and desire to secure by Letters Patent is:

1. In a mowing machine, the'combinationwith la truck, of an elevator frame, a knife mechanism carried by and arranged longitudinally of one side of said elevatorframe, means at the opposite side of the latter for pivotally connecting the said elevator frame to the said truck, so as to allow the elevator frame of being tilted on a transverse axis to raise and lower the knife mechanism with respect to the ground, an adjustable guide member carried by the truck and a sector shaped guide member carried by the said elevator frame, both said members movably engaging with one another and serving to guide the said elevator frame in the said tilting movement.

2. In a mowing machine, the combination with a truck, of an elevator frame composed of two sections foldable upon one another, a knife mechanism carried by andy arranged longitudinally of one side of one section, means at the opposite side of the said sectional frame for pivotally connecting the saidv elevator frame to the truck to allow the elevator frame of being tilted on a transverse axis to raise and lower the knife mechanism with respect to the ground and means for guiding the frame in the said tilting movement.

3. In a mowing machine, a foldable elevator frame, a truck supporting said frame and onto which the latter is to be folded, a shaft for the rear truck wheels, a removable extension for said shaft, means for connecting the said extension to the said shaft, means supporting said extension in the elevator frame,and a truck wheel capable of being interchangeably fixed to the said shaft and to the extension thereof respectively.

In testimony whereof I aflix my signature in presence of two witnesses.
